Well, I must agree the Pak 40 was a natural progression of, and very similar to the Pak38. It's easy to see that, and although this is the Pak38 here...it's the most definitive thing I've found..

(2) c. How to Operate
(1) Safety.-There are three mechanical arrangements which operate as safety devices: (1) unless the breechblock is properly closed, the safety plunger will not enter its recess and the gun cannot be fired; (2) the safety plunger must be in its recess in the lower face of the breech ring before the firing shaft can be rotated; (3) the breech cannot be opened if the striker is not cocked, because the firing shaft is engaged with the safety plunger, which is in its recess.
(2) To load and fire.-To open the breech by hand, recock the firing mechanism by turning the safe-and-fire lever to sicher ("safe") (fig. 66) and pushing it forward again; then turn the breech-mechanism lever in a clockwise direction. The breech will then be held in the open position by the extractors.
To load the gun, insert a round smartly. The round will then release the extractors, and the breech will close automatically.
To fire the gun,(1) press the push button in the middle of the elevating handwheel . If this fails, (2)pull the firing lever backward or (3)lift the plunger. *
A semi-automatic action operates when the plunger in the center of the front end of the spring case is pressed in and turned so that the word ein ("in") shows upward. When the plunger is set in this position, the breech is opened automatically during the counterrecoil. The gun is always recocked automatically during recoil. The breech is ready to close automatically when a round is slammed in.
* ok, I believe the evidence now, thanks for sticking with it(& me). designed to be fired by that button on the elevation wheel(you were right) FAILING that, it's fired by that lever my red arrow pointed at(I was right about that part).OR lift up on the plunger it says here. (nothing about a lanyard(I got that wrong)I noticed that fire lever your photo points at has a steel loop on it(making me wonder if a cord could be tied there if the Bowden cable wore out/ failed,ect... but nevermind....speculation again. Thanks again guys"
Very good details of the use of the Pak 38 at this site

In fact ~~great Intel. to be found there on lots of weapons--Bookmarked!

terminology can often get confused. As for seeing one of these fired...look around on YouTube, you might be able to locate a video of a re-enacting group operating one if you hunt hard enough. In-action film from WW2 invariably shows the gunner in position (as Mike mentions, he had to be able to watch the round going downfield to adjust fire) when the gun is being fired and he also obscures that whole side of the gun |

Yes , I've seen a number of videos, but none reveal the details of triggering of the round. Put Pak 40 in the YouTube search to find a few
